The preamplifier section features the latest implementation of AAVA volume control for further enhanced clarity. The instrumentation amplifier principle in the power amplification stage allows fully balanced signal transmission and realises a top-notch S/N ratio. Balanced Remote Sensing enables low impedance of output circuitry, resulting in a damping factor of 600. The power amplification stage uses power MOS-FETs in a triple parallel push-pull configuration, delivering 180 watts into 8 ohms for dynamic music enjoyment.

INTEGRATED STEREO AMPLIFIER
Since the E-303 launched in 1978, the high-power integrated amp has been at the core of the Accuphase product lineup. The E-480 is a successor model of E-470; it is the 11th generation of “Accuphase Core Product”. The E-480 Preamplifier section features the further evolved AAVA that enables accurate volume control. In the power amplifier section, a damping factor is further enhanced with precise and dynamic speaker driving ability. The preamplifier and power amplifier sections are kept entirely separate, and users can combine E-480 with other separate systems.

Option Boards
A range of sophisticated option boards opens up even more possibilities. The newly developed Digital Input Board DAC-40 features a USB port and support for high-bit, high-sampling frequency signals up to 192 kHz/24 bits. The newly developed Analog Disc Input Board AD-30 is also available, ideal for high-grade reproduction of analog records using either MC or MM phono cartridges.
